How to make it

1. Peel and roast sweet potatoes at 400°F for 45 minutes to an hour.

2. Meanwhile, add a splash of olive oil to a fry pan with a heavy base on medium-high heat. Add ground beef, pinch of salt, mushrooms, and curry powder. Cook mixture until meat browns. Add water and ketchup. Cook and stir for an additional 2 minutes on medium heat. Don't let the mixture become too dry — you're looking for a thick sauce-like texture. Remove from heat and set aside.

3. Cut open sweet potatoes. Spoon beef/mushroom mixture, a good dollop of sour cream, green onions, chili, and cilantro into each one.
